HOSE-COUPLING.

Specification of Letters Patent. Patented Sept. 30, 1913.

Application filed September 22, 1911. Serial No. 650,860.

To all whom it may concern I Be it known that I, Gin tunes GIovANNONI, "a citizen of the United States, residing at Enterprise, county of Wallowa, and State of Oregon, have invented certain new'and' which the following is a specification.

This invention relates to hose couplings. Garden hose is moved about and twisted during use which results in weakness and breaking where coupled to the outlet or pipe.

Myobject is to provide a novel swivel coupling adapted for convenient connection of a hose to the water supply pipe or outlet which will permit the hose to be moved about as desired and prevent any kinking or breaking thereof and thus relieve the hose of strain where connected to the water supply.

, With the foregoing object in view, the

invention consists of certain new features and combinations of parts, an example of In the accompanying drawings :Figure 1- shows the invention attached to a water supply faucet; Fig. 2, a longitudinal section through the device; Fig. 3, a cross section on line 3-3, Fig. 2; Fig. 4:, a detail section of the sleeve; Fig. 5, an end view thereof; Fig. 6, a face of the cushioning washer; Fig. 7, a similar view of the metal washer; Fig. 8, asect-ion taken lengthwise of the plug; and Fig. 9, an end view thereof.

The water outlet or supply pipe is shown at 1 and forms no part of my invention.

I provide an elbow 2 having a screwthreaded end adapted to engage the hose 1 and a screw-threaded part 4 in its other end which receives an externally screw threaded hollow plug 5 having an annular flanged head 6.

7 designates a loose sleeve which has a nut 8 so that it may be readily turned when connecting it to outlet 1 and which is a rorided with internal screw-threads 9 for the attachment of the screw-threaded end 10 of the outlet 1. A metal washer 11 bears race 13. Between the race or cone l3 and the Washer 11 are balls 14 which are retained in the race by a screw 15. A screw-threaded ring 11 engaging threads 9 holds the plug 5 and sleeve 7 in proper relative position but with the sleeve free to turn on said plug, a gasket or washer 16 may be used. The ring 11, on being suitably adjusted, limits the inward play of the sleeve on the plug 5. The screw-threaded mouth of the sleeve is unobstructed and free for attachment to the outlet 1.

in an annular flanged head at its other end,

asleeve having one end loosely and adjustably receiving the plug between the pipe elbow and the flanged head on said plug and prevented from detachment by the head of said plug, said sleeve being separated from the end of the elbow to com ensate for wear and having a part extending beyond the head of the plug and there provided with internal screw-threads of greater diameter than that of the head on the plug, to permit assembling, and an externally screw-threaded flat ring of hard material engaged with the internal screw-threads of the sleeve and located inwardly from the mouth thereof, leaving the screw-threaded mouth of the sleeve unobstructed for the attachm'ent of a pipe section, said ring being adjustable in saidsleeve and adapted to.

limit the inward play of the sleeve.

In testimony whereof, I hereunto afiix my signature in presence of two witnesses.
